Per API 618, 5th Edition, there are three Design Approaches to choose from, depending upon the reciprocating compressor’s application.
> DA1 Bottle sizing (design typically available in 24-48 hours)
> DA2 Pulsation (acoustical) analysis
> DA3 Includes DA2 and Mechanical Natural Frequency (MNF) Analysis and Forced Response Analysis, if required
Depending on the reciprocating compressor application, the following vibration studies may be required. BETA can provide these studies on a stand-alone basis, or as part of the studies in Part 1.
> Torsional Vibration Analysis
> Piping Flexibility and Stress (Thermal) Analysis
> Skid Design (lifting, loading, dynamic, optimized design)
> Small Bore Piping design or field assessment
> Offshore Structural Dynamics (platforms and FPSOs) or Foundation Design
> Other Studies (valve dynamics, bottle fatigue, etc.)
